IRF-IC’s 11 th Webinar on the subject “Revolution in Infrastructure Development by 3D Concrete Printing – Penetration of this revolution is insignificant so far; how to overcome the limitations and make it for routine adoption”
August 28 @ 4:00 pm - 5:30 pm
IRF India Chapter organized its 11 th Webinar of the webinar series, titled “Revolution in Infrastructure Development by 3D Concrete Printing – Penetration of this revolution is insignificant so far; how to overcome the limitations and make it for routine adoption” on 28 th August 2025 from 16:00 – 17:30 Hrs. The Webinar wasattended by Road Safety Professionals, Research Scholars, Corporates, Highway Engineers, Road Planners, Academicians, etc.
Prof. P.K. Sikdar, Advisor, IRF-IC, introduced and invited the Moderator of the webinar
Prof. N. Raghavan, Former Professor of Practice, IIT Madras.

Dr. Shashank Shekhar, Co-founder and CEO, MiCoB Pvt. Ltd., Click Here highlighted concrete is the most prevalent construction material due to its low cost and durability. MiCoB works extensively with Indian Defence, built 3D printed bunker to provide better protection to front-line soldiers guarding the country’s border with China in the Ladakh sector. 3D- printed permanent defences have been constructed and were trial tested against T90 tank as well. He also added some limitation of 3D-concrete printing which includes: Higher cost, Limited pilot projects, long term durability & structural performance data and lack of standards and testing protocols. He also explained the way forward for these limitations – Click here for complete presentation.
Dr. Biranchi Panda, Assistant Professor, IIT Guwahat, showed different concrete printing machines with their applications. He emphasized that Yield stress, viscosity and time dependent property were important for concrete printing. Printing can be improved
with nanoclay and due to its electrical attraction force, produced a denser microstructure, which corresponded to a higher static yield stress at rest. During flow, the viscosity decreased as the particles progressively separated and aligned in the direction of the flow due to electrical repulsion leading to improved printing. He explained that 3D-printing materials with higher binder content are prone to shrinkage,
lowers the sustainability and increases the cost. Click Here
